Title: Properties of Gases
Purpose: To analyze a few physical and chemical properties of gases as well as using those properties to identify the gases.
* For Hydrogen I placed a piece of Zn metal into a test tube with diluted HCl.
* To produce oxygen I added Hydrogen peroxide to manganese.
* Next, I added baking soda to vinegar. This caused a quick and energetic reaction! The gas from the reaction I pumped into some Limewater.
* Then I mixed Alka Seltzer and water and pumped the gas caused by that reaction into some limewater.
Data Table: Experiment Results |
Gas | Flame Reaction | Glowing Splint | Limewater reaction | Bromothymol blue reaction |
Hydrogen | It enlarged the flame. | | | |
Oxygen | It lit up quickly | | | |
Hydrogen & oxygen | It puts it out. | | | |
Carbon dioxide | It puts it out | | It bubbled and turned cloudy. | It turned it yellow |
Alka Seltzer | | | Bubbles stayed in the limewater. | |
Breath | | | Nothing happened | |

Balanced Chemical Equation for Oxygen and Hydrogen: 2H2+O2 2H2O
* The hydrogen reaction moved very slowly and I really couldn’t see anything happening. However, when I exposed it to flame, it lit up very well!
* The oxygen reaction began immidiatly once I added the manganese. It started fizzing a lot and the liquid turned…...

...PART A 1. Nuclear fission produces energy when energy is released from the breaking or splitting apart a large nucleus in smaller ones (breaks apart the nucleus). The total mass of the reactants is slightly more than the total mass of the products. 2. Nuclear reactors produce electricity from by using the heat from radioactive materials (fission reaction) to convert water into steam into a container that has fuel and the water. The water is then pumped through another container which has water to avoid the radioactive water coming in contact with the turbine. The heat from the primary water is used by the secondary water and water is then again, converted into steam. The secondary water is used to run the turbine generator to produce the electricity. The different components of a nuclear power plant are containment structure which houses the control rods, fuel rods, primary coolant, steam generator, pump and reactor vessel. When the steam flows out to the containment structure is passes through turbines, the condenser, condensate, secondary coolant and pump. From the condenser, warm water is pushed through to the cooling tower, then back to the body of water (water source). From the body of water, cooling water is passed through to the pump to carry it to the containment structure. From the turbine, steam is passed through generator, to release electricity for use. 3. The similarities between nuclear power plants and nuclear bombs are that they are......

...Georgia Institute of Technology CHEM 3700 Research Paper The German Energiewende “Die deutsche Energiewende“ Professor: Dr. Thomas Orlando Student: Shyam Rangarajan Abstract With the diminishing reserves of fossil fuels compounded by their negative effects on the environment, clean and renewable sources of energy to meet next generation energy demands undoubtedly need to be found. However an even more critical aspect governing global energy challenges is the way governments around the world take responsible actions and implement energy policies that are conducive to a sustainable future. A recent development in this regard is the German Energiewende, or Energy Transformation, one of the most ambitious projects of its type. The project aims to completely transition the German energy sector to one powered by renewables by the year 2050. Along with the benefits to energy security and controlled carbon emissions that such a policy would bring, the German government‟s efforts have also sparked a wide-scale increase in investment into emerging technologies. This has led to a vast increase in employment in the energy sector, and has also given rise to the concept of „prosumers‟, or individuals who produce and sell their own electricity through privately owned solar installations. Although the long term benefits of this project are enormous and the potential limitless, there are several short term repercussions that are slowing it down. Chief among these is the spiraling...

...Rajdeep Singh Chem 2A Fregrene The Evolution of the Battery and Electric Vehicle After reading various articles on battery chemistry and how it applies to electric vehicles’ I have come to a conclusion. Although electric vehicles may seem like a great idea for many people, because they can eliminate a great amount of emission pollutants in the atmosphere, they arrive with many unresolved issues. Issues which may be expensive as well as incovineient to solve. The first article I read was “Chemstry’s Electric Oppurtunity” by Alex Scott. In his article, he spoke of the automobile firm Tesla and their new Model S vehicle. The Tesla Model S is a vehicle capable of driving up to 300 miles before needing to recharge, compared to the majority of other electric cars who can only reach 100 miles. The CEO of Tesla Motors, Elon R. Musk claims that “anything a gasoline based vehicle can do, the Model S can do” (Scott, pg 1). Which may prove to be true since the car goes from ‘0-60 in only 4.2’ (Scott, pg 1). Many people wonder how the Model S is capable of outperforming other electric vehicles. It is due to the car’s large 670kg battery. This battery provides an energy density of 240 Wh/Kg. ‘This is much denser than the nickel based batteries of other firms such as Toyota, Nissan, and GM’ (Scott, pg 2). It’s great that Tesla is able to raise the bar in the electric vehicle field and provide a more efficient vehicle for consumers to enjoy, however there is a large inhibitor. Batteries...

...CHEM 111G – General Chemistry I Lab 1 Separation of the components of a mixture Aim of the experiment: To develop a stepwise procedure to separate the four components of a mixture of sand, salt, iodine and iron filings and determine the % of each by mass Brief procedure: The stepwise procedure was developed based on unique properties of each component: Salt: soluble in water Sand: insoluble in water Iodine: sublimes to vapor Iron: attracted to magnet We weighed out ~2g of the mixture in a 250mL beaker and chose to separate the iron first using a magnet. Since the iron sticks strongly to the magnet, the beaker + mixture was then reweighed to determine the mass of iron removed by difference. The iodine was then removed in the next step by placing the beaker on a hot plate covered by an ice cold evaporating dish and heating at maximum heat until no more purple iodine vapor were seen coming off. The deposited iodine crystals were recovered from the underside of the dish. Because some iodine is lost the beaker + mixture was then reweighed to determine the mass of iodine removed by difference. The remaining mixture of sand and salt was treated with deionized water to extract the salt (soluble). The sand was removed by filtration through a filter funnel via the water vacuum pump and the filtrate transferred to another weighed beaker. The salt was then recovered by evaporating the filtrate to dryness. The beaker was cooled and the salt mass determined by mass......

...Molecular Structures Molecular Structures Learning Objectives: - Understand covalent bonding displayed by elements in biological systems - Apply the octet rule - Practice converting molecular formulas into molecular structures - Be able to visualize and draw three dimensional molecular shapes Introduction: The octet rule states that most elements will share or exchange valence electrons in order to achieve a similar electron arrangement to the nearest noble gas. This concept is extremely important because it explains why elements bond to form compounds such as water, electrolytes, DNA, proteins and other biologically important substances. In this lab we will be focusing on a small palette of biologically important elements and studying how they covalently bond. In covalent compounds, the behavior of these elements tends to be consistent and predictable.
